A software system automatically and dynamically generates a fully functional user interface (UI) based upon, and connected directly to, an underlying data model (as instantiated within a relational database management system (RDBMS)). The UI derives from an automated interrogation of the RDBMS, and comprises all mode displays (e.g., browse, search, edit, add) for all tables, and a full complement of mechanisms—integrated directly into the mode displays—for representing, navigating, and managing relationships across tables, regardless of the complexity of the underlying RDBMS schema. It utilizes a hierarchical“context stack”for suspending the working state of a particular table while“drilling down”to work with related-table information and return relevant changes to the base table. The embodiment further provides methods to enhance and extend the internal representation of table structures, constraints, relationships, and-special requirements (“business rules”) for improved revelation of the schema structure through external interrogation.
